Product Overview
The MSP430G2302 is a Texas Instruments ultra-low-power mixed-signal MCU built around the MSP430 16-bit RISC CPU. The CPU includes 16 registers, a 51-instruction set, seven source addressing modes, and four destination addressing modes. Its instruction cycle time is 62.5 ns, and the internal digitally controlled oscillator supports operation up to 16 MHz.
Memory and peripheral resources include 4 KB Flash, 256 B RAM, one 16-bit Timer_A with three capture/compare registers, and one Universal Serial Interface supporting SPI and I2C. The MSP430G2302 device option does not include an ADC. Clock source options include an LF oscillator, DCO, VLO, 32-kHz crystal, and external digital clock, with four calibrated internal frequencies.
Package options include 20-PDIP, 20-TSSOP, 16-QFN, and 14-TSSOP. I/O availability depends on package: 16 I/O for MSP430G2302IN20 and MSP430G2302IPW20 options, and 10 I/O for MSP430G2302IRSA16 and MSP430G2302IPW14 options. Applications can include low-power SPI or I2C control nodes, capacitive-touch interfaces, and small embedded controllers requiring fast wake-up.
